material within a concrete or other cementitious Y slab 22. The panels 20 are held in spaced apart relation by the integral ribs 24 thereon. These ribs or the panels per se, are secured together by elements hereinafter described in detail by reference to Figs. '7 to 10 inclusive.

A blanket 2S of insulating material is held be tween the foraminous panels 2@ in spaced relan tion thereto for the purpose of establishing dead air space or air cells 28. The floor when so made is strong enough to support the weight to which it is subjected, will not sag, and presents air spaces and material of low thermal com ductivity.

Where extra rigid floor structure is desired, re-

inforcing rods 3B are laid at desirable intervals across the upper foraminous panel 25. In the illustrated embodiment of floor i6 (Figs. l and 2). reinforcing bars 3|) are laid upon upper panel 2d to intersect ribs 24 which bridge the distance between foundation l2 and girder Hl. These bars di? are long enough to likewise bridge the disn tance between an under-pinning such as a portion of the foundationwlg or a girder similar to that designated by the numeral ill.

The peripheral wallsr32 of the building rest upon floor l@ and maybe vtied thereto by inter connecting the foraminous panels 34E, of walls Vto foraminous panels 2|) of'iloor l5. Infact, the

panels 34 with' insulatingA blanket :it therebetween, may be erected ,upon panels Eifcf 'licei' i6 prior topouring orotherwise placing the upper layer ofrcernentitious substance 22. 4

Panels 3c are provided with'laterally projecting ribs 3&3 that project toward each other from the backs of panels M when they are in the operative position in parallelism and in spaced condition. is panels 34 are brought toge the lanket of insulating materiali isengaged by the bights of the U-shaped'ribs 38 and held taut to bridge the spa-ce'between proximal ribs $3. The type of insulating material 35 which is preferred is that havingsheets of building paper or the like di) forming a confining case for the insulating material 36. K Y

The blanket of insulating material 3i? is compressed between opposed ribs 38 and regardless of the type of interconnecting means that is em-v ployed, the ribsrare drawn tightly against the blanket ofinsulating material 35 and held in slightly Vspaced apart relation to insure that no metal-.toemetal contact of an appreciable amount is present. Thuathe possibility of heat ccnductivity is reduced to a minimum and the comn ponent parts of the'building structure not only insulated by Vnriaterial 33 but are filled with air cells d2 bounded by the blanket of insulating material 3b, a portion of theforaminous panels or 2t as the case may be, and ribs 38. Ribs iii arc devoidrof perforations Vand constitute adeguate load-bearing structural parts which in walls 35i, serve VasY studding or vertical frame members capable of receiving and holding a roof or upper floor weight. v

Foraminouspanels 34 and 26 employed in walls 52 and floor l'e respectively, are in the nature of expanded metal lath sheets, the longitudinal Vmarginal edges whereof 'are'in the form of a rib such as 24 or 358. f Y

Referring now particularly Vto wall 32 and having reference to yFig. 6 of the drawings, foraminousvpanels 3s areheld together by nesting the ribs formed Yalong the'proximal longitudinal Assuming the panels are twenty-four inches in width, it will be obvious that a structure weight supporting part in the nature of a studding, will be presented in wall 32 every twenty-four inches. ThisV weight supporting structural element will be a pair of nested ribs 38 on each side of the blanket of insulating material 3G. The ribs 38 are substantially U-shaped in cross Vsection and the bights of opposing ribs are in alignment and held together by clips or integral ears in a manner hereinafter specied.

When partitionV i8 is to be joined to an outside V wall 32, the vmarginal rib |38 of one or both of foraminous panels i3d and |35 thereof, is bent to enter a similar rib 38 of a panel 34 in the wall 32 to which the partition is joined. Reference to Fig. 6 indicates they manner in which panel |35 of partition it is secured to outside wall 32. In other words, as shown in Fig. 6, the panel |35 of partition i8 extends beyond that end thereof adjacent wall 32 and has a rib |38 disposed in nesting relation within a rib'3i of the inner panels of-wall 32.

It is contemplated that a hand tool be eine ployed in forming means for securing together the opposed panels of metallic foraminous ma terial. In Fig. l0 the bights of opposed ribs 38, having the blanket off Yinsulating material 3% therebetween, are Vfastened together by striking therefrom, ears 4d that are bent as illustrated. The ear ld struck from rib 38 to the right (Fig. lll), is forced through the blanket of insulating material 35, through opening IE6 formed by producing ear M on thevlefthand'rib 38, and thence downwardly into gripping condition. A number of such interlocking parts may be formed along each of the opposed pairs of ribs 38. U

In the form of interconnecting means illustrated in Fig. 9, fingers GB'are struck from the bight portion of one rib 38 and threaded through perforations 5G provided in the bight of opposing rib 38. These ngers 'pass through the blanket of insulating material 3b prior to their being bent into the condition illustrated to rigidly hold the' opposing ribs in a placeV where lateral movement is precluded. i 1V y InV Figs. 7 and 8 is illustrated a clip, broadly designated 52. This clip is`U-shaped and has legs 5s and a bight 56. n use this clip '32 has its legs 55 extended ,through opposed perforations 53 in the bight'sof opposite ribs 38 and through the interveningr blanket of insulating material Bil. The ends of legs 54 are bent to tightly hold the ribs together.

After the panels of foraminous material |34 and |35 in partition i8 and panels 34 of walls 32 are assembled, the facesrare coated with cementitious substance. Partition I3 andthe inner face of walls 32 will have a plaster or Vother` suitable inside finish 62 `applied while the vouter surfaces of walls 32 will have'concrete, stucco, or other selected cementitious material Ell applied to render the samer. weatherproof. Obviously, such plaster or the like 62 asis applied to the inner face of the building walls 32 and the faces of partitions I8, may be colored and finished to suit the taste of the owner.

When the cementitious coatings 52 and t4 are Y applied, any interlocking structure that has been employed is held against accidental displace-Y ment because the lcementitious substance enters and fills the hollowV ribs 38 to preclude straight- Y ening of ears 4t, fingers 48 or legs 54, as the case may be.

tact is created when employing any of the interlocking devices above described.

When ribs 33 constitute load-bearing structural elements, the rigidity and function is enu hanced by the concrete or other substance, which is introduced thereinto when the panels are faced. These load-bearing elements produced by ribs 38, therefore, extend substantially the full width of the partition, wall or floor when the building is erected.

It is possible to manipulate the expanded metal lath having ribs 33 or 24 as the case may be, to produce walls or building structure parts of a wide variety of dimensions without losing the advantages arising from the combination of ribs, panels, interlocking means, cementitious substance, insulating material, and air cells. The invention, therefore, is flexible and capable of use when erecting most any type of enclosure.

The fragmentary illustrations of building structures, shown in the oiicial drawings, accompanying this specification and forming a part hereof, are for illustrative purposes only, and therefore, it is desired to be limited in the einbodiment of this invention only by the scope of the appended claim'.

Having thus described the invention, what is claimed as new -and desired to be secured by Letters Patent is:

In building structure, a pair of relatively perpendicular walls, said walls each comprising a pair of spaced, metal lath, sectional panels, each of the sections having a number of spaced, inwardly extending, V-shaped, hollow ribs integral therewith, the outermost ribs of each section being in nested relationship with proximal ribs of sections next adjacent thereto, the ribs of one panel being aligned with the ribs of the opposite panel and having their apices spaced apart; a continuous partition comprising -a Pair of spaced, paper sheets having resilient insulating material therebetween disposed in compressed relationship between the ribs of said panels; a number of interconnecting elements passing through said apices of the aligned ribs and through said partition, said ribs being otherwise imperforate; and a coating of cementitious material on the outermost face of each panel respectively, said coatings filling the ribs in locking relationship to said elements, one of the ribs of one wall extending into nesting relationship with one of the ribs of the other wall, the cementitious coatings of said one wall merging with the proximal coating of said other Wall whereby to join the walls as a unit.
